okan 6fd1cc10d9 Original idea from Dimitris Papastamos to move windows to corners a while ago;
re-proposed by Julien Steinhauser with an updated diff. Apparently this was in
the original calmnwm.

However, expand the original idea and let clients 'snap' to edges instead,
neatly allowing key bindings that snap to adjacent edges (i.e. corners) as
well. No default bindings assigned.
